Lambie doesn't have to apologise for Abbott attacks: Wang

Palmer United Party senator Dio Wang said his colleague Jacqui Lambie did not need to apologise to the Prime Minister for calling him a ''political psychopath'', but said Tony Abbott was a ''decent man''.

Senator Wang said that Tasmanian Senator Lambie was a ''very straightforward person and she speaks her mind''.

''I think that's a good quality of any politician, to be honest,'' he told reporters outside Parliament House on Friday

''Personally I wouldn't use such language, I think he's [Mr Abbott] a decent person trying to do his job.''

Senator Lambie has taken swipes at Mr Abbott this week as the rookie MPs arrived for orientation sessions at Parliament House before the new Senate sits for the first time on Monday.

On Thursday, Senator Lambie criticised Mr Abbott for "parading his daughters around" during the 2013 election campaign and has previously called Mr Abbott a ''political psychopath''. She has also called the Prime Minister a ''bare-faced, uncaring liar''.

Senator Lambie, on Friday took another swipe at Mr Abbott, declaring the Prime Minister needs ''a bucket of cement'' to toughen up if he couldn't cop her criticism.

The political rookie isn't fazed by the stir she's caused, and has offered Mr Abbott some free advice about how to handle critics.

''If you're not used to attacks by now then you probably shouldn't be in that position,'' she told the Nine Network on Friday.

''You've got one of two choices. You can run and hide or you can say to yourself 'here's a bucket of cement – toughen up'.''

She also rejected suggestions she'd crossed the line by dragging families into the political argy bargy, rehashing her belief that Mr Abbott put his daughters at risk during the election campaign.

The former military police officer said there was a fine line between enlisting your family's support and ''parading'' them for political gain.

''Let's face it, they are really three gorgeous looking girls,'' she said of Mr Abbott's daughters.

''I can only hope that they can stay safe but I guess we'll see what happens in the future.''
